Summary
Finite-volume conjugate heat transfer simulations with a k-ω turbulence model, validated against published experiments, were used to tune the height and glass-to-absorber gap of a solar chimney with two air channels for maximum airflow. The best design, 2 m tall with a 0.125 m gap, reached about 38.5% thermal efficiency; its optimal gap is narrower than that of a conventional chimney.
